Induction of the unfolded protein response by α-synuclein in experimental models of Parkinson's disease.

Accumulation of misfolded proteins in the endoplasmic reticulum (ER) is the main event leading to the induction of the ER stress-related unfolded protein response (UPR). Recent postmortem evaluation, showing that the UPR pathway is activated in nigral dopaminergic neurons bearing α-synuclein inclusions in the brain of Parkinson's disease (PD) patients… CONTINUE READING
